I Need Help. How To Stop Smoking Weed

I have been smoking weed for 11 years now, and with in those 11 years I missed out on an estimated 10-14 days of smoking it... Sounds ridiculous I know, but trust me I had what I considered reasons for it at the time, and gradually I made excuses to keep the habit going, now I'm stuck in a rut of constant anxiety and depression, I know marijuana is the trigger but at the same time I feel the NEED to smoke it on a constant basis, I get extremely edgey without it and have no habit or ability to sleep, it even gets to the point where I stare the clock down and consider it reward able when I hold myself back for even two hours. No exaggeration I am use to smoking 6-18 grams of potent weed A DAY!, I am from Vancouver BC so buds are around in abundance and are easily obtainable.
Marijuana has taken over my life, I am no longer the social butterfly I once was, instead I am paranoid and afraid of what people think or say about my thoughts or opinions. I am always worried about my status in life, or the lack of. It bothers me I am so content with so little. Every night I battle my own brain telling myself " tomorrow we will do better, tomorrow we won't need weed" and by morning.. My first thought upon waking up is " where is the weed or how do I get it?" This doesn't seem like much to many people, but for me it's almost a disability, I abused a substance that once helped me and now I am living a low quality of life because of it.
I am open to ideas and methods for quitting smoking, but the Internet has proved to be useless on the subject, seeing as so many people feel it's not addictive or that it's not that bad of a habit. I also notice that people who claim to have a problem are smoking very small amounts on a not so frequent basis.. If anyone has gone through this or is on their way to managing it do you have any tips beyond the obvious?
You sound like a garden variety addict to me.

I suggest you look up your local NA group(s) and attend a couple of "open" meetings.
You will meet a room full of folks just like you and they will show you how they are recovering.

Open meetings are speaker meetings and you just have to sit and listen, you will hear your story told repeatedly.

I've been living in Vancouver for almost 4 years now, weed is available EVERYWHERE. I can't take it anymore, it's getting to a point where im convinced ive failed at life, i cant recognize myself, im not the person i was before weed became such a huge part of my life..
I used to smoke only a few times within a year when i first started at 16, it used to be a special occasion, i would never buy it myself (only smoked when friends shared with me), and i would make one regular sized joint last a week (not joking, one puff was enough to get me high).
I began to notice a significant increase in my tolerance, i started to smoke joints like cigarrettes, i bought a pipe then a bong.. All at once i was smoking at home by myself and just enjoying doing the chores or going for a walk, doing groceries etc because it was more fun that way. Nowadays i smoke before having dinner, before showering, before i go to the movies.. Even a couple of hours before leaving for class.

What kills me is that my fiancee is a heavy smoker and has been for years.. We need to quit asap and im thinking about going to one of these meetings because i need to surround myself with people that are going through the same hell as we are.. I feel like i cant talk about this problem with anyone, especially in a city where EVERYBODY SMOKES. I feel lonely, i cant make new friends because i dont think im interesting/smart/funny enough, and the only time i do feel like "myself" is when im high.

Sorry about any mistakes, im typing on my phone in a hurry because you said youre from Vancouver. It would be nice to chat sometime, i'll keep an eye on this thread if you want to connect.
Try to stay positive!
